IMPROVEMENT IN DOOR-BELLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit may concern:

Be it. known 4that we, ELrsHA H. GOLDMAN and DAVID W. HrsnY, of Kansas, in the county of Edgar and State of Illinois, have invented a new and valuable Improvement in Door-Bells; and we do hereby declare that the following` is a full, clear, andv exact description of the construction and operation of the same, reference being hadto the .annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a'frcnt view of our invention.

Figure 2 is a central vertical Asection thereof. I

Our invention relates to au improvement in knockers for doors, and consists in the combination there` with of a bell, whereby the beauty and reliability of the kuocker, together with the sweet tone of 'a bell, are secured. Also, in thel use of a reversible hammer, whereby, in case of sickness, a muffled sound can' be produced by the adjustment.

The letter A ofthe drawings designates the knocker, which may be made as ornamental as may be desired.

B designates the striker thereof', arranged to impinge against the arm O of 'the lever D, to which the hammer-head Eis attached. It should be of rubber or leather.

F represents the bell secured tothe door on the inside, in the manner shown.

A rest, a, is provided for the long arm of' the lever of the hammer.

The head E of' the hammer isl made easily reversi# ble. Vhen the metal face is adjusted to strike the bell, a clear, loud tone is produced, the strength of which is in proportion to the size of the bell employed. I

In order to produce ia muled or softer sound, a

rubber armature, Z, is employed. rIlhis is attached to the other side of the head, in order that it may come into operation when the head is reversed.

In order to afford free play to the arms of the hainmer-lever, an opening, K, is made through the wood of the door. This-is covered on the outside by the plate' of the knocker. Other 'arrangements for producing communication between the striker of the knocker and the lever of the hammer may be made,- whereby soA large 'an-opening will be unnecessary. A simple perforation for the passage of a connecting-rod may be sucient.

, We do not desire to confine ourselves to the precise arrangement herein described; but

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In combination with the door-knocker A, the hammer E and bell F, substantially as shown and described. v

2. In combination with the bell F, the hammer herein described, provided with reversible head E, having,r a muling armature, Z, as speciiiedl- 3. In combination with the bell F and hammer E, the knocker A, provided with the deadening-pad B, as specified.

In testimony that we claim the above, we have hereunto subscribed our names in the presence of two witnesses.
